Letters Patent No. 65,526, dated June 11, 1867.

IMPROVED FIRE-ALARM.

TO ALL WHOM IT MAY CONCERN:

' ,Be it known that we, W. W. Annnnws, J. Gunmen, J. GANWEILER, and J. STENGEL, of Croton, Michigan, have invented certain new and useful improvements in' Fire-Alarms; and we declare the following to be a full, true, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Figure 1 represents a plan of a house, with the covering or roof removed, to which our alarm is attached.

Figure 2 represents a side view of the weights, and shows the manner in which they are attached to the lever.

Letter A represents the frame of a house, which is divided into a number of rooms. Letter 13 represents a cord, which passes around the entire circuit of each room, and is securedalong the top of the walls. In order to render this cord not only more inflammable, but proof against insects and vermin, it is covered with a coating of pitch. Before this cordB leaves the room in which it is placed, it is fastened to rod or wire C, for the purpose of preventing a false alarm being given. Should a room, through which a nnmber of these cord pass, happen to catch on fire, these cords would all be severed, thus serving only to delude the watchman and to make him think that a larger part of the house was on fire than really was. To prevent mistakes of this kind, wires or rods have been fastened to the cords before passing into the next room, so that should there be a fire in one room the flame would sever only the .cord that was intended for thatroom. Letter D represents a chain, which is fastened to each of the wires or rods for the purpose of allowing them to pass the more readily and easily overthe rollers E, in order that the alarm, in case of fire, may be given as soon as possible, and before the flames have made any headway. These wires are all intended to pass into one room as public as possible, or into one where there is a watchman for that purpose. Attached to each of wires or rods is a weight, F, which should be of snificient heaviness to draw the chains over the rollers the moment the cord is cut. These weights are attached to the chains by means of loops. Each room in the house should be numbered, and a corresponding number should be placed upon the weight that is attached to the wire or cord which passes from the room, so that when onc'of the weights falls a person has only to glance at the number upon the weight, and he knows in an instant in what part of the house and in what room the fire is. Letter G represents a lever, one end of which passes through the loops which are attached to theweights, and the other is intended to catch in a common clock-alarm. The moment that one of the weights fall it jerks the end of the lever out of the cogs of the alarm-wheels, and the alarm is set in motion. Letter H represents a box, which is placed immediately under the weights so as to receive them as they fall. This alarm can be attached to either public or private dwellinghousos, it matters not how large, orhow many rooms there are in them. 7

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is

1. The employment of cords B B, when said cords are saturated with some inflammable material for the purpose of more effectually enabling them to be consumed or severed in case of fire, substantially as described.

2. The employment of rods C C in the manner specified, for the purpose of indicating the exact room or locality in which the fire originated, in combination with lever G and weights F F, substantially as described.

In testimony whereof we aflix our signatures in presence of witnesses.
